----------------------------------------

    Description: 
I have a realtime peer behind NAT. Things work perfectly. I then did an asterisk reload, which caused the peer cache to be cleared, I then attempted to reach the peer. The private IP address from the Reg. Contact was copied over to the IP address, which caused the peer to be unreachable.
